Detection of convergence in data sets with ancient and recent transitions to arid environments. (A) Phylogenetic relationships of the subset with recent (within genera) transitions. The environments and families of the species are color-coded as in Figure 2, and the dates of transitions are indicated. (B) Phylo-PCA plot and PCA plot using family-corrected expression values. (C) Heatmap representing eigengenes per species and per coexpression module. (D) Differentially expressed genes called by DESeq2 and genes detected by the Eve model (genes passing the FDR threshold are only found in the nonoverlapping genes as shown with the small gray bar). (E–H) Same for the set with ancient (between genera) transitions.
